1 The Colorado portion of Project 0042 has been digitized twice. See Utah for the other version.
2 See Utah Project 0042. Projects 0128 and 0262 are fully merged with Utah Project 042.
3 See Project 0603. Project 0636 is fully merged with 0603.
4 Only the part of Project 0672B south of 39° was digitized.
5 Project 1120 may contain parts of digital Projects 3163 and 4067.

Description of Table

No.: Internal USGS identification number
Name: Internal project name (not always the name used in publication title)
Flown By: Company or government agency who flew the original survey
Spacing and Dir.: Primary flight-line spacing and primary flight-line direction
Altitude: Primary flight altitude in feet; B = barometric elevation, AG = above ground draped over topography
LnMi.: Approximate total of line miles flown for this survey
Datum: Indicates if a regional field was removed and, if it could be determined, the base value removed. Total field = no regional was removed. Arb. (arbitrary) datum = the base value removed was not stated on the map.
Publication: Brief publication reference*. USGS publications are listed as: Open-File reports = xx-yyyy where xx is the publication year, Bulletins and Professional Papers = B-yyyy or P-yyyy, Geophysical Maps = GP-yyyy, Miscellaneous Field Studies Maps = MF-yyyy, Miscellaneous Investigations Maps = I-yyyy, Unpub = unpublished data, refers to all or part of the original project area.

*For more complete references see: Hill, P.L., 1991, Bibliographies and location maps of publications on aeromagnetic and aeroradiometric surveys for the states east of the Mississippi River south of the Ohio and Potomac rivers, U.S. Geological Survey Open-File Report 91-0370-D, 67 p.
